DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG.
It comprises a container body 1 and a container lid 2, and the container lid 2 can be freely opened and closed by a hinge structure with respect to the container body 1. On the open sides of the container body 1 and the container lid 2,
A concave portion 3 is formed in the outer wall on the mating surface side, and a locking device 4 is provided in the concave portion 3. As shown in FIGS. 3 and 4, the container body 1 and the container lid 2 have a hollow double-walled structure obtained by blow molding or vacuum molding a thermoplastic resin. 5 is a suspension belt.

[0011] the locking equipment 4, as shown in FIGS. 2 to 4, made of a movable lock part 7 provided in受爪6 and the container body 1 formed in the outer wall of the container lid 2 The movable hooking piece 7 has a base end side supported by the container main body 1 by the guide rotating arm 8 and has a hooking claw 9 on the distal end side which is engaged with the hooking claw 6. That is, the guide rotating arm 8 that supports the movable latching piece 7
Are a pair of right and left parts, which are integrally formed by a connecting plate 10, which is fixed to the base end of the movable hooking piece 7 by a shaft 11, and which is fixed to a mounting base 13 on the container body 1 side by a shaft 12. Has been stopped. The mounting base 13 is engaged and fixed to a mounting portion 14 integrally formed on the outer wall of the container body 1. Reference numeral 15 denotes a packing on the mating surface, and 16 denotes a protrusion fitted to the packing.

As shown in detail in FIGS. 5 and 6, a mounting portion 14 integrally formed on the outer wall of the container body 1 and a mounting base 13 engaged with and fixed to the mounting portion 14 have a plurality of engaging claws respectively engaged with each other. 17 and 18 is intended to have a mounting engage a plurality of engaging claws 17, 18 together to the mounting portion 14 by the lateral slide and along the mounting base 13 to the mounting portion 14 within the recess 3 The base 13 is fixed. Therefore, the engaging claw 17 of the mounting base 13 has a protrusion, and the engaging claw 18 of the mounting portion 14 has a groove.
Mounting base 13 which engage fixed to the mounting portion 14, as kana Akira et al shown in FIGS. 3 and 4, is mounted a load in the direction of separating the mounting base 13 at best receive the locking structure . Reference numeral 19 denotes a rivet for stopping the lateral movement of the mounting base 13. A portion for fixing the guide movable arm 8 of the mounting base.
Reference numeral 21 protrudes from the mating surface 20 of the container body 1,
The mounting base 13 can be guided on the mating surface 22 of the lid 2.
A recess 23 is formed in which a portion 21 for locking the moving arm 8 is locked.
Have been. Therefore, the container lid 2 is
In the closed state, the portion 21 engages with the recess 23.
Stop, and then the guide rotation arm 8 moves beyond the dead center of the shaft 12.
Since the hook 9 of the movable hook 7 is fastened to the hook 6,
It is ensured that the container lid 2 is held in a high closed state with respect to the container body 1.
Is preserved.

The mounting structure of the mounting base 13 may be configured as shown in FIG. That is, in this embodiment, the mounting base 13 is locked and fixed from the mating surface 20 of the container body 1 to the inner surface of the inner wall. Since the mounting base 13 has a structure covering the mating surface 20 of the container body 1, the protrusion 16 fitted to the packing 15 is attached to the mounting base 13.
Is formed. The mounting base 13 may be fitted after the container body 1 is formed, or may be mounted by insert molding with the mounting base 13 installed in a container forming mold at the time of forming the container.

In order to lock the locking device 4 constructed as described above, the movable latching piece 7 is operated from the state shown in FIG. 4 to the state shown in FIG. When the movable hook 7 is further pushed toward the container main body 1 side, the guide rotating arm 8 exceeds the dead center of the shaft 12, so that The hooking claw 9 of the movable hooking piece 7 is fastened to the receiving claw 6 and is locked and held so as not to be detached. By the way, in this locking process, the guide rotating arm 8 is attached to the mounting base 13 about the shaft 12 by the mounting portion 1.
Although a load is applied in a direction to separate from the container body 4, the mounting portion 14 is integrally formed with the container body 1 and the mounting base 13 is locked to the mounting portion 14 in a direction against the load.
Even if a large load is applied to the mounting base 13, there is no possibility that the mounting base 13 will be detached from the mounting portion 14.

In the present invention, the container main body or the container lid means the one container half provided with the movable hooking piece with the container main body and the receiving claw irrespective of the position, arrangement or depth of the storage portion. The other half of the container provided is referred to as a container lid.
